摘要：

Two gene targeted markers i.e. CAAT box-derived polymorphism (CBDP) and start codon targeted (SCoT) polymorphism were applied to analyze the genetic stability of in vitro propagated plants of Bauhinia racemosa Lam. multiplied by enhanced axillary shoot proliferation of mature tree derived nodal explant. Nine randomly selected micropropagated plants of 1year age were subjected to molecular analysis. The isolated genomic DNA samples were subjected to PCR amplification with a total of 61 primers (25 CBDP and 36 SCoT) out of which 39 primers (21 CBDP and 18 SCoT) produced scorable amplicons. A total of 97 and 88 clear, distinct and reproducible amplicons were produced by CBDP and SCoT primers, respectively. The monomorphic banding pattern obtained through all the tested primers corroborated the true to type nature of in vitro propagated plants of B. racemosa.
